Following are a number of back-translations of Romans 11:33:

• Uma: “Really no kidding is the big life [glory] of God! No kidding is the clearness of his heart [i.e., wisdom] and his knowledge! Who can ask-thoroughly about all his purposes! Who can investigate all his works!” (Source: Uma Back Translation)
• Yakan: “God’s mercy to us (incl.) all is really unimaginable/unspeakable. His knowledge/wisdom is very deep and he knows all! We (dual) cannot understand his thinking/mind. We (dual) cannot understand his deeds.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “God’s kindness is very great. His wisdom and His understanding cannot be fathomed (the word fathomed literally means to sound the depths of a pool or a body of water with a stick, but it’s also used figuratively in this way). People cannot understand what He does and nobody can explain what He is doing.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “God is indeed rich in mercy! Neither is there any limit to his wisdom and what he knows. Even any person is not able-to-understand properly what he has decided to do and the way he fulfills what he decided.” (Source: Kankanaey Back Translation)
• Tenango Otomi: “No one can come to know all the great good God has. No one can know how great is his wisdom. No one can know how great are his thoughts. Because no one can come to know well about how God does.” (Source: Tenango Otomi Back Translation)
